I think I got the tapes labeled properly. I can see that the
parameters that got invoked on my previous attempt with the "-o
tpchanger=" were not correct. Thus, an error in block size on the re
labeling. But I think I at least understand how that happened.

In the research storage section, you should add:
tapepool "research"
to tell amanda that the research storage can use any tape in the
research pool.
Then
amanda@marlin:~/daily$ amlabel -f --pool research --assign daily
"Bio-Research-[0-9][0-9][0-9]"
Setting Bio-Research-001
changed it to
0 Bio-Research-001 reuse BARCODE:000001L7 BLOCKSIZE:512
POOL:research STORAGE:research CONFIG:daily
But, `amcheck daily` did not make any mention of the research storage
or tapes

You must tell amanda which storage to use, in amanda.conf:
storage "daily" "research"
to tell it to use both storage
And, when Amanda ran last night, it appears to be running according to
the previous normal without any effects from my changes in the
configuration and disklist. The backups are going to the LTO6 tape
library in the default "daily" storage.

I've attached my amanda.conf and disklist so that you can see what
I've done. I put the tag for the storage "research" in the DLEs. I
started with the herbarium entries, and expect to continue through
many others once it works.
Since it appears that on this system (with its rapidly escalating disk
array space) compression is the bottleneck; I decided to try letting
the LTO7 do it's own compression. Thus the herbarium dump definition
that I'm using has no compression.
The daily storage have no dump-selection setting, so all dles (even
those tagged Research) will go on the daily storages.
The dle tagged Research will be written to both storages.
You need to add a dump-selection for the daily storage and add a
corresponding tag to all dles that must go in that storage, you should
add it in a dumptype inherited from all dles.

Thank you! I've got that set up now.
I tried labeling tapes. I thought it was working. e.g.:
You should never use the '-o tpchanger=' argument, it is always
better to use '-ostorage='
That will set the storage and the pool correctly.
amanda@marlin:~/daily$ amlabel -f -o tpchanger=NEO200x48 -o
'labelstr="^Bio-Research-[0-9][0-9][0-9]*$"' daily
"Bio-Research-001" slot 1
Reading label...
Found label 'amtapetype-206980288' but it is not in the tapelist file.
Writing label 'Bio-Research-001'...
Checking label...
Success!
After that (which I repeated for several tapes), I tried
amanda@marlin:~/daily$ amlabel --storage research --assign daily
"Bio-Research-[0-9][0-9][0-9]"
Bio-Research-001: Can't assign storage without force, old storage is
'daily'
[etc. for each of the several tapes]
So, adding -f
amanda@marlin:~/daily$ amlabel -f --storage research --assign daily
"Bio-Research-[0-9][0-9][0-9]"
Bio-Research-001: Can't assign storage because it is a new labelled
tape.
[etc. for each of the several tapes]
All labels already correctly set.
Changing the storage is useless, but we could allow amlabel to change it.
And looking at the tapelist, I see entries like:
0 Bio-Research-001 reuse BARCODE:000001L7 BLOCKSIZE:2048 POOL:daily
STORAGE:daily CONFIG:daily
A label is not bound to a storage, the listed storage is the latest
storage that used that tape,
A tape is bound to a pool, and it can be in any storage that use that
pool.
Have I done something wrong? Or is that going to work, because it is
a blank tape. In other words,
since it is only accessible via tpchanger=NEO200x48, which is in the
definition of the storage
research; will it be accessed by those backups with the tag research
and then re listed in the
tapelist as belonging to storage research?
I also wasn't finding much detail in the man pages on the
implications of pools. I don't have any
such designations in my amanda.conf.
A pool is just a name, a storage will use any tape that is in the
same pool.
